Find dy/dx by implicit differentiation. x2 − 8xy + y2 = 8
2 answers:
We have that
x² − 8xy + y²<span> = 8
</span>2x-8y-8x(dy/dx)+2y*(<span>dy/dx)=0
</span>8x(dy/dx)-2y*(dy/dx)=2x-8y
[8x-2y]*(dy/dx)=2x-8y
(dy/dx)=[2x-8y]/[8x-2y]
(dy/dx)=2*[x-4y]/2*[4x-y]
(dy/dx)=[x-4y]/[4x-y]
the answer is
(dy/dx)=[x-4y]/[4x-y]
Answer:

Step-by-step explanation:
The denominator is always the variable that we want to find the derivation in relation of. So it is always dx.
The number is the variable we derivated. So
